Since the first sector of the disk is loaded into ram at location 0x0000:0x7c00 and executed, without this jump, the processor would attempt to execute data that isn't code. Even for non-bootable volumes, code matching this pattern (or using the E9 jump opcode) is required to be present by both Windows and OS X. To fulfil this requirement, an infinite loop can be placed here with the bytes EB FE 90. */

The official FAT Specification from Microsoft says that this field is really meaningless and is ignored by MS FAT Drivers, however it does recommend the value "MSWIN4.1" as some 3rd party drivers supposedly check it and expect it to have that value. Older versions of dos also report MSDOS5.1, linux-formatted floppy will likely to carry "mkdosfs" here, and FreeDOS formatted disks have been observed to have "FRDOS5.1" here.
